Suspension Maxx MAXX CAM 3 Leveling Kit

Does your truck suffer from front-end fatigue? Want to add a new set of off-road tires, but don't have the clearance? Add Suspension Maxx's patent-pending Maxx Cam leveling kit, and custom calibrate the suspension travel of your vehicle's front end.

MAXX Cams are an innovative 2-piece adjustable torsion bar suspension levers engineered to allow you to calibrate the suspension travel of your vehicle's front end up to 3 inches. Use it to restore lost ride height, as a result of torsion bar fatigue, or to increase front end clearance, enabling you to choose more aggressive off-road tires. Want a lowered look? MAXX Cams can be used to reduce the suspension travel of the front end, and lower it.

Winner of the 2006 SEMA best new product and made in America, the Maxx Cam 2 is manufactured from 4140 alloy steel. Designed for heavy duty and off road use, each Maxx Cam 3 is heat treated to ensure added strength.

Customer Q&A - SuspensionMaxx SMX-MC3

I am looking for a 2 inch lift for my 2006 GMC 2500 HD front suspension only looking to lower my differential also

This kit will not fit a 2006 GMC 2500 HD. The correct kit is a SMX-MC2HD but the leveling or lift kits for those models do not require the differential position to be changed until a 4" lift height so the SMX-MC2HD will not include hardware to drop the differential. At this time we do not carry a leveling kit for a 2006 that includes differential drop hardware.

do u need to get wheel aliment after

Yes, with any suspension modification an alignment is recommended immediately after installation to avoid tire wear.

Hi. So it appears I cannot use the Max 3 on my 2009 Duramax. Only the max 2. Without all the spacer options the 3 offers, how to avoid the control arm issues and clearance with stop issue and differential angle problem with my truck? I want to level my truck but not crest ride issues and bad angles on ball joints and differential. I'm confused. Thanks, Bob

The Maxx Cam 2 is the correct model for 2009 Chevy 2500HD and 3500HD. I spoke with Suspension Maxx about your concerns. On these models, they recommend staying in the 2" lift range to avoid clearance issues with the bump stops. At the 2.5" setting it will be closer to the maximum travel for the stock suspension components and you can run into some issues. If the torsion bars are at their stock setting now and no one has increased the adjuster bolts. At the 2" setting you should have no issues with balljoint and differential angles.

Do you sell anything to level my 2009 Chevy HD?

We do have leveling kits for a 2009 Chevy HD. The SMX-MC2HD fits the 2009 Chevy 2500 HD and 3500 HD.

Will it fit a 2500 hd Chevy 4x4 extended cab. 2013

Yes, the SMX-MC3 will fit the 2013 Chevy 2500HD 4X4, extended cab.

Will this work on a 2016 2500 HD?

Suspension Maxx Leveling kit SMX-MC3 will not work on the 2016 2500 HD. You will need kit SMX-MC5 for the 2016 Chevy Silverado or GMC Sierra 2500HD or 3500 4x4.
